“…The main CCT advantages compared with CMR are the feasibility and short examination time. Therefore, CCT is particularly useful in patients with relative and absolute contraindications for CMR or in the case of claustrophobic patients, which may be unable to undergo the examination [ 27 , 28 ].…”

“…CCT allows the evaluation of the main cardiac morphological parameters, such as volume, mass, and wall thickness. The values demonstrated excellent reproducibility and a very good linear relationship compared to those obtained with CMR, even if the normal CCT values are significantly lower than those obtained with CMR [ 28 ]. The knowledge of the normal ranges is essential for the differential diagnosis between AH and cardiomyopathy.…”

“…The knowledge of the normal ranges is essential for the differential diagnosis between AH and cardiomyopathy. Normal values of LVEDV and LVESV were, respectively, 112.9 ± 26.1 mL and 41.7 ± 14.7 mL, the normal value of LV mass was 145.0 ± 29.1, and the normal values of the septal and posterior wall thicknesses were, respectively, 1.08 ± 0.18 cm and 0.91 ± 0.15 cm [ 8 , 28 ].…”

Cardiac Imaging in Athlete’s Heart: The Role of the Radiologist

Athlete’s heart (AH) is the result of morphological and functional cardiac modifications due to long-lasting athletic training. Athletes can develop very marked structural myocardial changes, which may simulate or cover unknown cardiomyopathies. The differential diagnosis between AH and cardiomyopathy is necessary to prevent the risk of catastrophic events, such as sudden cardiac death, but it can be a challenging task. The improvement of the imaging modalities and the introduction of the new technologies in cardiac magnetic resonance (CMR) and cardiac computed tomography (CCT) can allow overcoming this challenge. Therefore, the radiologist, specialized in cardiac imaging, could have a pivotal role in the differential diagnosis between structural adaptative changes observed in the AH and pathological anomalies of cardiomyopathies. In this review, we summarize the main CMR and CCT techniques to evaluate the cardiac morphology, function, and tissue characterization, and we analyze the imaging features of the AH and the key differences with the main cardiomyopathies.

Knowing the patient's current cardiovascular disease (CVD) status, as well as the patient's current and future CVD risk, helps the clinician make more informed patient-centered management recommendations towards the goal of preventing future CVD events. Imaging tests that can assist the clinician with the diagnosis and prognosis of CVD include imaging studies of the heart and vascular system, as well as imaging studies of other body organs applicable to CVD risk. The American Society for Preventive Cardiology (ASPC) has published “Ten Things to Know About Ten Cardiovascular Disease Risk Factors.” Similarly, this “ASPC Top Ten Imaging” summarizes ten things to know about ten imaging studies related to assessing CVD and CVD risk, listed in tabular form. The ten imaging studies herein include: (1) coronary artery calcium imaging (CAC), (2) coronary computed tomography angiography (CCTA), (3) cardiac ultrasound (echocardiography), (4) nuclear myocardial perfusion imaging (MPI), (5) cardiac magnetic resonance (CMR), (6) cardiac catheterization [with or without intravascular ultrasound (IVUS) or coronary optical coherence tomography (OCT)], (7) dual x-ray absorptiometry (DXA) body composition, (8) hepatic imaging [ultrasound of liver, vibration-controlled transient elastography (VCTE), CT, MRI proton density fat fraction (PDFF), magnetic resonance spectroscopy (MRS)], (9) peripheral artery / endothelial function imaging (e.g., carotid ultrasound, peripheral doppler imaging, ultrasound flow-mediated dilation, other tests of endothelial function and peripheral vascular imaging) and (10) images of other body organs applicable to preventive cardiology (brain, kidney, ovary). Many cardiologists perform cardiovascular-related imaging. Many non-cardiologists perform applicable non-cardiovascular imaging. Cardiologists and non-cardiologists alike may benefit from a working knowledge of imaging studies applicable to the diagnosis and prognosis of CVD and CVD risk – both important in preventive cardiology.

BackgroundHepatic alterations are common aftereffects of heart failure (HF) and ventricular dysfunction. The prognostic value of liver injury markers derived from cardiac MRI studies in nonischemic dilated cardiomyopathy (DCM) patients is unclear.PurposeEvaluate the prognostic performance of liver injury markers derived from cardiac MRI studies in DCM patients.Study TypeProspective.PopulationThree hundred fifty‐six consecutive DCM patients diagnosed according to ESC guidelines (age 48.7 ± 14.2 years, males 72.6%).Field Strength/SequenceSteady‐state free precession, modified Look‐Locker inversion recovery T1 mapping and phase sensitive inversion recovery late gadolinium enhancement (LGE) sequences at 3 T.AssessmentClinical characteristics, conventional MRI parameters (ventricular volumes, function, mass), native myocardial and liver T1, liver extracellular volume (ECV), and myocardial LGE presence were assessed. Patients were followed up for a median duration of 48.3 months (interquartile range 42.0–69.9 months). Primary endpoints included HF death, sudden cardiac death, heart transplantation, and HF readmission; secondary endpoints included HF death, sudden cardiac death, and heart transplantation. Models were developed to predict endpoints and the incremental value of including liver parameters assessed.Statistical TestsOptimal cut‐off value was determined using receiver operating characteristic curve and Youden method. Survival analysis was performed using Kaplan–Meier and Cox proportional hazard. Discriminative power of models was compared using net reclassification improvement and integrated discriminatory index. P value <0.05 was considered statistically significant.Results47.2% patients reached primary endpoints; 25.8% patients reached secondary endpoints. Patients with elevated liver ECV (cut‐off 34.4%) had significantly higher risk reaching primary and secondary endpoints. Cox regression showed liver ECV was an independent prognostic predictor, and showed independent prognostic value for primary endpoints and long‐term HF readmission compared to conventional clinical and cardiac MRI parameters.Data ConclusionsLiver ECV is an independent prognostic predictor and may serve as an innovative approach for risk stratification for DCM.Evidence Level1Technical EfficacyStage 2
